Tony Stark / Iron Man

Eccentric genius, billionaire, philanthropist Tony Stark is the armored super hero known as Iron Man. Decompressing from his heroic, near-self-sacrificial action as Iron Man that saved New York City from annihilation, Tony finds himself unable to sleep and plagued by worry and trepidation. When his world is destroyed and those closest to him threatened, Tony must find a way to save them—and in the process find himself again. via Marvel

Succinctly put, Stark refers to himself as a "genius, billionaire, playboy philanthropist," but he is most notably the current CEO of Stark Industries, a weapons and technology company founded by his father Howard Stark. As Iron Man, however, Tony is considered a controversial hero whose mission statement is to make the world a safer place to live. He has been described as reckless, narcissistic and someone who doesn't play well with others, but Stark has proven himself competent time and again through numerous conflicts and negotiations.
